I suggested a friend's old P3 Dell Inspiron may be quicker running Ubunto. I repartioned and formatted the hard drive before realising there was no CD player. How do I now reinstall an OS? The hard drive connection is not the same as my Dell Lattitude so I can't swop drives. I've tried USB supporting boot disks but still can't access USB devices. Is there any other way to install Ubunto or other OS? I've tried Duse boot and an Iomega version. USB is assigned a drive letter but when I run DOSUSB.COM (part of the booting routine) the system hangs. How do I restore the machine?
